SES on my 2004 Oldsmobile Alero
2.2 liter
Check engine
codes = Misfire
The vehicle was just in a front corner collision
Changed spark plugs
GM tech = jk
question = I just had a collision in the front driver side corner of my
vehicle, everything is pretty much cosmetic, but after the collision
the car started idling funny, and lacks power when i push the gas, and
is really hard to start in the mornings. Went to auto zone and the
guy said it was a mis fire code, and to change my plugs and it would
fix it, i did, and it did nothing, is there a sensor or something that
could make the car act this way? That could have possibly been messed
up in the wreck, thank you so much
JK:
The damage really should have nothing to do with it. Nothing on that part of the car to cause
misfiring. You may want to get it scanned again and note which cylinders are missing, and if
possibly another code or more. 2 common things that cause this condition on the 2.2 are the
ignition module, or the ignition coil housing cover (shell). Normally 2 cylinders will go out at the
same time because the internal circuits fire 1-4, and 2-3 as a pair. That would explain the no
power, idle, and hard start. It does sound as if you are running on only 2 cylinders. Not
something you just want to put a part on and hope it fixes it, it will need to be diagnosed by a
good technician. Let me know if you need further assistance.
